-----------------------------------------
Summary: Reference resolution for large number of columns should
be faster
Key: SPARK-16406
URL: https://issues.apache.org/jira/browse/SPARK-16406
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 2.0.0
Reporter: Herman van Hovell
Assignee: Herman van Hovell
Resolving columns in a LogicalPlan on average takes n / 2 (n being the number
of columns). This gets problematic as soon as you try to resolve a large number
of columns (m) on a large table: O(m * n / 2)
